Question about Cars & Trucks
Usually the problem is a bad ground connection, in the wiring harness or in the tail lamp assembly.

Unfortunately, could not find owners manual for 1996.
Website only has models 2004-current
There are two fuse boxes. One under driver compartment usually left to the steering colum. A label is stamp to identify each fuse. I would look at Park Lights and Instrument Cluster fuses. The easy way is to take a flashlight and look at all fuses. If they are all okay. Then just remove the Park Lights and Instrument Cluster fuse and reseat them. The other fuse box is under the hood and near the batter. It also has a label to identify each fuse.

Id look at the headlight switch and do some voltage tests to see whats coming out of there. Pay close attention to any wires which look like someone was in there already.People can mess stuff up faster and better than the vehicle can by itself!

Jeep Grand Cherokees are famous for this problem. Tell me about it, I have had 3 (2001, 2004, 2006). The connections on these vehicles are not of the best quality. I have not had to deal with '06, but '01 and '04 were constantly going out.
There are two main causes (you can change the bulbs as many times as you like and they will only last a couple of weeks, with luck more than that). Check the end of the cables that connect to the brake lights, sometimes they tend to "burn" and short, and need to be changed. The most common cause is the contacts of the bulb holder to the light housing assembly, they tend to wear and/or get really dirty, these you can buy very inexpensive from your local Mopar parts dealer.
Since you have a problem with the 3rd brake light also, I would be more inclined to check the wiring.

I agree with shannongreer but also check on the swith at the back of the brake pedal. It's near the top of the pedal almost under the dash.

First, I want to say thank you for the info, you saved me money and aggravation. Second it took mea little while to figure out what contact I was looking for. So I would like to provide a little more detail to make it easier for others in the future.
This is the corrective method for your brake lights not working when your headlights are on(2000 Jeep Cherokee Larado).
1) The cause of the problem is heat from the bulb.
2) Remove the light assembly as if you were going to change a bulb.
3) Turn the socket and remove it from the taillight assembly and set it aside(check to be sure your bulb is not burnt out).
4) Look at the opening, you will see 3 flat chrome colored contacts on the assembly.
5) Notice the one by it self at the top of the opening, that is the "ground".
6) If you look closely you will notice the plastic around the ground contact has shrunk a little bit, this caused the contact to pull away from the socket, causing the problem.
7) With a small flat head screwdriver, VERY GENTLY pry up the contact so it stays slightly upward by itself.
8) Re-insert the bulb assembly back into the housing and press your brake petal with your lights on.
9) You should be in good to go!
10) Tools: Phillips head screwdriver and a small flat head screwdriver.
11) Time : 5 minutes per light
